Product Details
General Description
The MIC3223 is a constant current boost LED driver capable of driving a series string of high power LEDs. The MIC3223 can be used in general lighting, bulb replacement, garden pathway lighting and other solid state illumination applications.The MIC3223 is a peak current mode control PWM boost regulator and the 4.5V and 20V operating input voltage range allows multiple applications from a 5V or a 12V bus.
Features
• 4.5V to 20V supply voltage• 200mV feedback voltage with an accuracy of ±5%
• Step-up output voltage (boost) conversion up to 37V
• 1MHz switching frequency
• 100mΩ/3.5A internal power FET switch
• LEDs can be dimmed using a PWM signal
• User settable LED current (through external resistor)
• Externally programmable soft-start
• Protection features that include:
– Output over-voltage protection (OVP)
– Under-voltage lockout (UVLO)
